From 8b89fc40039b9fbb5e1b529d2c1e3b58bf820845 Mon Sep 17 00:00:00 2001 From: Nuno Sa Date: Tue, 27 Apr 2021 10:54:49 +0200 Subject: [PATCH] iio: adis16475: do not return ints in irq handlers On an IRQ handler we should not return normal error codes as 'irqreturn_t' is expected. This is done by jumping to the 'check_burst32' label where we return 'IRQ_HANDLED'. Note that it is fine to do the burst32 check in this error path. If we have proper settings to apply burst32, we might just do the setup now so that the next sample already uses it.
